The nature of the invention consists in the peculiar shape of the shingle, it being so constructed that a portion of the shingle at the butt, (consisting of such portion as is laid or exposed to the weather, which is -generally about one third of the length on the upper side, as from Z) to c and a perfeet straight surface on the under side as from a to c. In making a shingle thus, it gives more thickness at the point Z) where the layerneXt above begins, and thus gives a longer wear to it by the abrasion of rain, and snow, than can be had by the shingle made in the common form.
